Rent Affordability Calculator

How much rent can I afford in the UK?

This calculator helps you understand the maximum monthly rent that keeps your finances healthy — based on your income and actual monthly outgoings. It uses the widely-accepted 30–35% income rule as a guide.

London rents are significantly higher than the national average. Outside London, the same budget typically covers more space. If you are renting in London, budget at least 20–30% more than these figures suggest.

Your affordability is broadly in line with the UK average

You are well-positioned to afford a home, rent, or car within the typical UK range. Small improvements to expenses or savings will open up more options.

Recommended rent budget

£1,125 – £1,313per month

Up to £1,313/month keeps your finances healthy based on the 30–35% income rule. This is comfortable for most people at this income level.

What these figures mean

30

Lower end (£1,125/mo) — 30% of gross income. Leaves good room for savings and unexpected costs.

35

Upper end (£1,313/mo) — 35% of gross income. Workable if your other outgoings are low. Anything above this may start to feel like a stretch.

Safe monthly disposable income

£2,475per month

After expenses and debt, you have around £2,475 left — with a 10% buffer included for unexpected costs.

Why the 30% rule?

The 30% rule — keeping rent below 30% of gross income — has been used by financial advisers and housing economists for decades. It's a practical threshold that leaves enough money for food, transport, savings, and unexpected costs.

In practice, many UK renters — especially in London — spend 35–50% of income on rent. While that's common, it often means cutting savings, going into debt for emergencies, or having very little financial flexibility.

If you must go above 35%: reduce other fixed costs where possible (phone contract, subscriptions), avoid car finance on top of high rent, and build a small emergency fund first.

These figures are based on gross salary. Your take-home pay after tax will be lower, which means the real percentage of take-home going to rent will be higher than the 30% figure suggests. Use the disposable income figure above as the more practical check.
